Abstract
-
PURPOSE: To evaluate the effect of the systemic osteoporosis on radiographic density of alveolar bone and cortical thickness of mandible
MATERIALS AND METHODS
The bone mineral density values of lumbar and femur were measured by dual-energy X-ray absorptiometry and T scores of lumbar, femur were obtained respectively. Radiographic densities of alveolar bones and panorama mandibular index(PMI, represents as cortical thickness) were analysed statistically according to age and T score variavles.
RESULTS
The radiographic density of alveolar bone of maxillary molar showed significant difference by age and femur T group. That of mandibular molar showed significant difference between femur T group. Panorama mandibular index showed significant difference between age groups. CONCLUSON: The radiographic density of alvealar bones was more dependent on age femur T than lumbar T. Cortical thickness of mandible was correlated with increasing age.
